Aortoesophageal fistula: report of a successfully managed case and review of the literature

Abstract

Aortoesophageal fistula is a rare, frequently fatal cause of upper gastrointestinal bleeding. Although several causes have been described, it appears that the most common cause is rupture of a thoracic aortic aneurysm into the esophagus, occurring in approximately 12% of thoracic aneurysm ruptures. Although the entity was originally described in 1818, the diagnosis has rarely been made before death, and until 1983 no one survived surgery for aneurysm-associated aortoesophageal fistulas. Since that report of two cases, only two other survivors, including this patient, have been reported. Included herein is the report of a successfully managed case, along with a discussion of the causes, clinical features, and diagnostic approach to the disease, as well as the management of both the aortic and esophageal components of the fistula.
